THREAD-GUIDE MECHANISM FOR SPINNING OR TWISTING MACHINES.

Specification of Letters Patent.

Patented Jan. 23, 1906.

Application filed December 10, 1904. Serial No. 236,296.

To all whom it may concern:

Be it known that we, OSCAR L. OWEN and J QHN F. SNELLING, citizens of the United States, residing in Whitinsville, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Thread-Guide Mechanism for Spinning or Twisting Machines of which the following is a full, true, and concise specification.

This invention relates to thread-guiding mechanism for spinning or twisting machines, and has for its object the provision of simple and practicable apparatus possessing various features of advantage and importance, whereby the thread-guides are properly and adjustably supported and the entire apparatus is specially guarded against the accumulation thereon of fly or fluff.

The invention also involves other features of improvement in construction and relative arrangement of parts, as will be hereinbelow fully described, and more particularly pointed out in the appended claims.

In the accompanying one sheet of drawings which forms a part hereof, Figure 1 is a perspective view, with parts broken away, of the thread-board in position upon a spinning-machine frame. Fig. 2 is a view of a modified form of thread-guide. Figs. 3, 4, and 5. are respectively illustrations of the bolts, nut, and clamping-washer for holding the threadguide. Fig. 6 is a detailed view ofthe backrail hinge. Fig. 7 is a detail of a back-railsupporting-bracket, and Fig. 8 is a central transverse cross-section on the line 8 8 of Fig. 1.

The reference character A represents an ordinary roller-beam common in spinning and twisting machines, and the thread-board back rail B is mounted on said beam by means of hinges G, which latter are provided with slots in their lower leaves receiving fastening-bolts by means of which said hinges, and consequently the back rail and parts carried by it, are rendered adjustable with reference to said roller-beam. The upper leaf K of the hinge G is suitably secured to the under side of the back rail B, which is in this manner capable of pivotal motion with respect to said rollerand downwardly to expose parts of the appathread produce unsightly and ratus beneath. One or more brackets H, fastened at convenient points to the roller-beam beneath the back rail, serve to support the latter and hold it from swinging lower than a horizontal position, and these brackets, furthermore, are efficacious in preventing injury or distortion of the hinges G in the event of an unusual or accidental strain upon said back railas, for example, by the violent slamming of the said rail into position. The said back rail is comprised of a flange or angle-iron running substantially the entire length of the roller-beam A, and the forward depending flange thereof constitutes a support upon which the thread-guide holders O are mounted. The latter are each constructed of a sinple piece of sheet metal stamped to have a flat top surface, with depending flanges on all four sides thereof. The side flanges c c are perforated in the region of their rearward upward corners, as at Z), for the reception of a hinge-wire F, which latter is common to a number of holders passing through each and is secured to the back rail through the interposition of a long hinge-plate D. The plate D is composed of a straight sheet-metal strip secured by the bolts I to the depending front flange of the back rail and provided with upwardly-extending ears or butts jfor receiving and holding the hinge-wire F. Preferably these butts are alternated with the guideholders along the length of the hinge-wire, and the said flanges a a serve as stops engaging this hinge-plate D to hold the guide-holders in proper horizontal position, as shown in Fig. 1. The downturned back flange c of the guide-holder is formed thereon at a sufficiently rearward point to overlap the hingewire, and the said flange has suflicient vertical dimension to form a closure for the space between the holder and the back rail, as clearly shown in Fig. 8, thereby preventing accumulations of fluff or other foreign matter in the joint between the holder and rail, which foreign matter would otherwise be likely to fall down upon the yarn and becoming twisted with the injurious bunches in the finished fabric. The closure of this space by the downturned flange c, moreover, permits free and unobstructed passage thereover of the cotton-Waste used to wipe these parts and obviates the possibility of portions of the waste becoming caught in the hinges. The front flange c is provided with a notch d or hole d for receiving and holding the thread-guide wire E.

In the form shown in Figs. 1 and 8 the guide is provided with an oblong loop openended at one end in the form of a hook to receive the bolt f, set in a squared hole a in the top of the plate (7. The loop is clamped against the under side of the holder by the washer la, and nut 9, being in this manner adjustably held with relation to the said holder 0 and also easily removable therefrom by virtue of the open end of the loop. In the form shown in Fig. 2 the thread-guide is formed with its inner end bentinto the form of a closed loop in axial alinement with the shank of the guide. In this form the nut g is dis posed centrally with respect to the guide-holder and is therefore more accessible for the application of a wrench.

In the construction as above described it Will be observed that we have produced exceedingly simple and reliable apparatus, which is capable of all of the usual and required manipulations and adjustments and yet may be easily maintained in cleanly and satisfactory condition.

Having described our invention, What we claim, and desire to secure by United States Letters Patent, is

1. A thread-guiding mechanism for spinning or twisting machines comprising a back rail and thread-guide holders hinged thereto and formed of sheet metal with downturned side flanges, ahinge-wire piercingsaid flanges, and a downturned back flange covering said hinge-wire and closing the space between the holder and said back rail, substantially as described.

2. In a thread-guiding mechanism for spinning or twisting machines,a sheet-metal holder composed of a flat top with downwardly-turned side flanges forming stops and having apertures in the rearward upper corners thereof, in combination with a hinge-wire passing through said aperture, and a back flange on said holder forming a protective covering for said hinge-wire between the side flanges, substantially as described.

In testimony whereof we have signed our names to the specification in the presence of two subscribing witnesses.
